The Corporate Trustee is responsible for oversight of Mesabi Trust's risks from cybersecurity threats as it relates to financial record keeping, cash and investment management, administration and reporting.  The Corporate Trustee also serves as registrar and transfer agent for the Trust.  The Corporate Trustee has dedicated personnel responsible for assessing and managing Mesabi Trust’s cyber risk management efforts, informing senior management of the Corporate Trustee regarding the prevention, detection, mitigation and remediation of cybersecurity incidents and supervising such efforts.  The Corporate Trustee’s information technology team has significant experience selecting, deploying and operating cybersecurity technologies, initiatives and processes and relies 3
Table of Contentson threat intelligence as well as other information obtained from governmental, public or private sources, including external consultants engaged by the Corporate Trustee to monitor the prevention, detection, mitigation, and remediation of cybersecurity incidents.  The Corporate Trustee works with leading firms in the cybersecurity industry, leveraging their technology and expertise to monitor and maintain the performance and effectiveness of products and services that are used by the Corporate Trustee.  The Corporate Trustee maintains a cyber risk management program designed to identify, assess, manage, mitigate, and respond to cybersecurity threats, which processes are integrated into the Corporate Trustee’s overall risk management process.  The Corporate Trustee maintains robust cybersecurity protocols including, but not limited to technological capabilities that prevent and detect disruptions, computer workstations and programs protected with passwords and passphrases, as well as employee training throughout the year on financial regulations and cybersecurity followed up by testing of that knowledge.  The protocols are based on recognized best practices and standards for cybersecurity and information technology.  The Corporate Trustee has an annual assessment, performed by a third-party vendor, of the Corporate Trustee’s cyber risk management program.  Other non-technical protocols include securing of documents and work areas that could contain non-public information and independent verification of information changes by outside vendors.  Mesabi Trust faces risks from cybersecurity threats that could have a material adverse effect on its financial condition, results of operations, cash flows or reputation.  The Corporate Trustee has experienced, and will continue to experience, cyber incidents in the normal course of its business.  However, prior cybersecurity incidents have not had a material adverse effect on Mesabi Trust’s financial condition, results of operations, or cash flows.

(“Cliffs”), (jointly, the “Operator”), the lessee/operator of the leased lands.  The arbitration proceeding was commenced with the American Arbitration Association (“AAA”).  The Trust seeks an award of damages relating to the Operator’s underpayment of royalties in 2020, 2021 and 2022 by virtue of the Operator’s failure to use the highest price arm’s length iron ore pellet sale from the preceding four quarters in pricing internal production during the fourth quarter of 2020 through 2022.  The Trust also seeks declaratory relief related to the Trust’s entitlement to certain documentation and to the time the Operator’s royalty obligation accrues.  During 2023, the parties appointed a three-member arbitration panel and engaged in discovery.  The AAA evidentiary hearing took place in March 2024.  Post-hearing briefs will be exchanged in May 2024, and post-hearing oral arguments, if any, will take place in June 2024.ITEM 4.            MINE SAFETY DISCLOSURES.Not applicable.4

As disclosed previously, on May 1, 2023, Baker Tilly US, LLP notified the Trustees of Mesabi Trust that it will not stand for re-appointment as the independent registered public accounting firm of Mesabi Trust.  On June 21, 2023, Mesabi Trust engaged Boulay, PLLP as its independent registered public accountant to audit Mesabi Trust’s financial statements.ITEM 9A.         CONTROLS AND PROCEDURES.Evaluation of Disclosure Controls and Procedures.  The Trust maintains a system of disclosure controls and procedures designed to ensure that information required to be disclosed by the Trust in the reports that it furnishes or files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and regulations of the Securities and Exchange Commission.  Due to the pass-through nature of the Trust, the Trust’s disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by Mesabi Trust is received from Cliffs and its wholly-owned subsidiary, Northshore.  In order to help ensure the accuracy and completeness of the information required to be disclosed in the Trust’s periodic and current reports, the Trust engages certified public accountants, geological consultants, engineering firms, and attorneys.  These professionals hired by the Trust advise the Trust in its review and compilation of the information in this Form 10-K and the other periodic reports filed by the Trust with the SEC.5
Table of ContentsAs part of their evaluation of Mesabi Trust’s disclosure controls and procedures, the Trustees rely on quarterly shipment and royalty calculations provided by Northshore and Cliffs.  Because Northshore has declined to provide a written certification attesting to whether Northshore has established disclosure controls and procedures and internal controls sufficient to enable it to verify that the information furnished to the Trustees is accurate and complete, the Trustees also rely on (a) an annual certification from Northshore and Cliffs, certifying as to the accuracy of the royalty calculations, and (b) the related due diligence review performed by the Trust’s accountants.  In addition, Mesabi Trust’s consultants review the schedule of leasehold royalties payable, and shipping and sales reports provided by Northshore against production and shipment reports prepared by Eveleth Fee Office, Inc., an independent consultant to Mesabi Trust (“Eveleth Fee Office”).  Eveleth Fee Office performs inspections of the Northshore mine and its pelletizing operations, observes production and shipping activities, gathers production and shipping information from Northshore and prepares monthly production and shipment reports for the Trustees.  Furthermore, as part of its engagement by Mesabi Trust, Eveleth Fee Office also attends Northshore’s calibration and testing of its crude ore scales and boat loader scales which are conducted on a periodic basis.As of the end of the period covered by this report, the Trustees carried out an evaluation of Mesabi Trust’s disclosure controls and procedures.  Based on this evaluation, the Trustees have concluded that such disclosure controls and procedures are effective.Trustees’ Report on Internal Control over Financial Reporting.  The Trustees’ Report on Internal Control over Financial Reporting is set forth on page F-2 of the Annual Report.  This Annual Report on Form 10-K does not include, and is not required to include, an attestation report of our independent registered public accounting firm on internal control over financial reporting based on an exemption from such rules related to the Trust’s status as a smaller reporting company and non-accelerated filer. Changes in Internal Control over Financial Reporting.  To the knowledge of the Trustees there were no changes in the Trust’s internal control over financial reporting that occurred during the Trust’s last fiscal quarter that has materially affected, or is likely to materially affect, the Trust’s internal control over financial reporting.  The Trustees note for purposes of clarification that they have no authority over, and make no statement concerning, the internal controls of Northshore or Cliffs.ITEM 9B.         OTHER INFORMATION.Rule 10b5-1 Plan and Non-Rule 10b5-1 Trading Arrangement Adoptions, Terminations, and Modifications.  During the three months ended January 31, 2024, none of the Trustees adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408 of SEC Regulation S-K.ITEM 9C.         DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS.Not applicable.​6
Table of ContentsPART IIIITEM 10.          DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE.The Agreement of Trust dated July 18, 1961, as amended by the Amendment to the Agreement of Trust dated as of October 25, 1982 (the “Agreement of Trust”) provides for a Corporate Trustee and four individual Trustees (collectively, the “Trustees”).  The Trust does not have, nor does the Agreement of Trust provide for officers, a board of directors or any committees.  Generally, the Trustees continue in office until their resignation or removal.  Any Trustee may be removed at any time, with or without cause, by the holders of two-thirds in interest of the Certificates of Beneficial Interest in the Trust (the “Trust Certificates”) then outstanding.  In the case of an individual Trustee, a successor is appointed if the individual Trustee dies, becomes incapable of acting or is adjudged bankrupt or insolvent.  In the case of the Corporate Trustee, a successor is appointed if a receiver of the Corporate Trustee or of its property is appointed, or if any public officer takes charge or control of the Corporate Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation.  Successor Trustees can only be appointed by the holders of a majority in interest of the Trust Certificates then outstanding.  Because such appointments are not made on a regular or periodic basis, the Trust does not have a standing nominating committee or a policy in place for the recommendation and nomination of successor Trustees.The Trust’s activities are limited to collecting income, paying expenses and liabilities, distributing net income to the holders of Trust Certificates (the “Unitholders”) after the payment of, or provision for, such expenses and liabilities, and protecting and conserving the assets held.  The Trustees have adopted a Code of Ethics that applies to the Trustees.  A copy of the Code of Ethics is incorporated by reference in Exhibit 14 of this Form 10-K.  We intend to disclose any amendments to and any waivers from a provision of our Code of Ethics on our website within four business days following such amendment or waiver.The Trust has not designated a separate audit committee comprised of independent committee members relying on an exemption provided by Rule 10A-3 of the Securities Exchange Act of 1934, as amended.  As such, the Trustees have not designated an “audit committee financial expert.”  The Trustees collectively perform the functions of an audit committee.To carry out the Trustees’ duties under the Agreement of Trust, the Trustees meet on at least a quarterly basis to discuss information and circumstances relevant to the Trust.  The Trustees also conduct telephone conferences from time to time between the quarterly meetings to address developments that require more timely attention.  The Trustees held 15 meetings either in person or via teleconference in fiscal 2024.  All of the Trustees attended at least 75% of the sum of all Trustee meetings held in fiscal 2024.In the third quarter of each year, the Trustees also conduct an annual inspection trip in which they personally visit and tour Northshore’s mining operations and plant facilities located near Babbitt and in Silver Bay, Minnesota, respectively.  During the inspection trip, the Trustees meet with and interview Northshore personnel with respect to Northshore’s current operations, changes in operations, mining plans, capital equipment and facilities.Because Mesabi Trustees are appointed until they resign or are removed, at the time of nomination the Trustees believe that it is necessary for each Trustee to possess many qualities and skills.  Set forth below are the present Trustees’ principal occupations and directorships held with other public corporations during the past five years, or longer as material, their ages and the year each of the Trustees was first elected as a Trustee of the Trust.7

In addition, she has experience in securities law and general corporate law.The Trust believes that each of the individual Trustees has a diversified background and extensive financial, business and industry specific expertise that make them an important resource in the oversight of the Trust’s affairs.  There are no family relationships among any of the Individual Trustees.ITEM 11.          EXECUTIVE COMPENSATION.Compensation Discussion and AnalysisThe Trust does not have a board of directors, executive officers or any employees.  The compensation paid to the Trustees is governed by the Amendment to the Agreement of Trust dated October 25, 1982, as amended (the “Amendment”).  The Amendment does not provide for any stock awards, option awards, non-equity incentive plan compensation, change in pension value, nonqualified deferred compensation earnings or any other compensation.  The Trust does not have severance agreements nor does it provide post-retirement benefits to the Trustees.  Accordingly, all such tables have been omitted from the Annual Report.Pursuant to the Amendment, each individual Trustee receives at least $20,000 in annual compensation for services as Trustee.  Each year, annual Trustee compensation is adjusted up or down (but not below $20,000) in accordance with changes from the November 1981 level of 295.5 (the “1981 Escalation Level”) in the All Commodities Producer Price Index (with 1967 = 100 as a base).  The All Commodities Producer Price Index is published by the U.S. Department of Labor, Bureau of Labor Statistics.  The adjustment is made at the end of each fiscal year and is calculated on the basis of the proportion between (a) the level of such index for the November preceding the end of such fiscal year, and (b) the 1981 Escalation Level.  Any action to modify or otherwise vary the compensation of the individual Trustees as provided by the Amendment must be approved by the affirmative vote of 66 2/3% in interest of the Trust Certificates then outstanding.  Each of the individual Trustees received total compensation of $51,413 during fiscal 2024.Under the Amendment, the Corporate Trustee receives annual compensation for services as a Trustee in an amount equal to the greater of (i) $20,000, or such other amount determined in accordance with the adjustments described in the preceding paragraph, or (ii) one quarter of one percent (1/4 of 1%) of the trust moneys, exclusive of proceeds of sale of any part of the Trust Estate (as such terms are defined in the Agreement of Trust), received by the Trustees and distributed to Unitholders.  The compensation paid to Deutsche Bank Trust Company Americas, for services as Corporate Trustee of the Trust, under this first prong of this compensation formula was $51,413 pursuant to the Amendment.Additionally, each year the Corporate Trustee receives $62,500 to cover clerical and administrative services to Mesabi Trust, other than services customarily performed by a registrar or transfer agent for which the Corporate Trustee is paid additional service fees.  The Corporate Trustee earned $113,913 in cash compensation for the fiscal year ended January 31, 2024, inclusive of the $62,500 administrative fee.  The Corporate Trustee also received $4,381 for its services as registrar and transfer agent for the year ended January 31, 2024.  Accordingly, the Corporate Trustee earned $118,294 in total compensation for the fiscal year ended January 31, 2024.Under the Amendment, the Individual Trustees may, in extraordinary circumstances, pay additional compensation to the Corporate Trustee.  The decision to pay such compensation must be unanimously approved by the Individual Trustees.  The Corporate Trustee did not receive any compensation for extraordinary services with respect to the fiscal year ended January 31, 2024.9

Table of ContentsITEM 13.          CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.Related Person Transaction PolicyDuring the fiscal year ended January 31, 2024, the Trustees met on at least a quarterly basis and reviewed and approved or ratified certain transactions that occurred during each of the prior fiscal quarters.  In connection with their review of the Trust’s transactions, the Trustees consider whether there have been any related person transactions.  In determining whether to approve a related person transaction, the Trustees consider the following factors, in addition to any other factors they deem necessary or appropriate:●whether the transaction is expressly permitted by the Agreement of Trust;●whether the terms are fair to the Trust;●whether the transaction is material to the Trust;●the role of the related person in arranging the related person transaction;●the structure of the related person transaction; and●the interests of all related persons in the related person transaction.The Trust maintains a written related person transaction approval policy, which sets forth the Trust’s policies and procedures for the review, approval or ratification of any transaction required to be reported in Mesabi Trust’s filings with the Securities and Exchange Commission.  The policy applies to any financial transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships in which Mesabi Trust is a participant and in which a related person has a direct or indirect interest.Certain types of transactions, which would otherwise require review, are pre-approved by the Trustees in accordance with the policy.  These types of transactions include, for example, (i) transactions, when aggregated with the amount of all other transactions between the related person and the Trust, that involve less than $120,000 in a fiscal year; (ii) transactions where the interest of the related person arises only by way of a directorship or minority stake in another organization that is a party to the transaction; (iii) transactions with a related person involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services; and (iv) a transaction that is specifically contemplated by provisions of the Agreement of Trust.Based on their review of the Trust’s transactions during the fiscal year ended January 31, 2024, the Trustees concluded that there were no related person transactions required to be disclosed in this Annual Report on Form 10-K.Pass-Through Royalty Trust ExemptionsBecause of its legal structure and character as a pass-through royalty trust, the Trust is exempt from Rule 10A-3 of the Securities Exchange Act and the Corporate Governance Standards set forth in Section 303A of the New York Stock Exchange’s Listed Company Manual.12
